Application filed May 18,1925. Serial No. 31,097;

To all whom it may concern: 1

Be it known that I, GEORGE. CLAUsING, a citizen of the .United States,residing at Portsmouth, in the county of Scioto and State of Ohio, haveinvented certain new and useful Improvements in Lasts, of which thefollowing is a specification, reference being had therein to theaccompanying draw- My invention relates to lasts and in particular to alast which will stay in either In detail, it is my object to provldelast which will have a combined lever and spring and in which the lastparts will be connected together by a link, the link being connected tothe last part on one side, by an anchor pin and on the other s detothelever wh ch car ries the sprmg and 1s connected pivotally It is, afurther object to have the spring engage with the first mentioned anchorpin. It is an additional object to have the pivotal point of connectionof the link to the lever and the aiichor pin .on which the link ispivoted and against which the spring abuts so arranged that a line drawnbetweentheir centers will pass over the center of ,movement of the lastparts when they are moved from one position to the other.

Referring to the drawings: Figure 1 is aside elevation partially insection, disclosing the link, lever, and spring mechanism of, the last;

Figure 2 is a plan v1ew partially in section of the link, lever andspring mechanism mounted on the anchor pins which are brokeniaway andshown only for a portion of their length.

Referring-to the drawings in detail, 1 is a toe part having a cut awayportion or groove 2, cut in its instep portion, such groove having anouter open end along the rear face 3 of the toe part. Transverselylocated across this open mouth of the cut away portion 2 and across therear .face of the last part 1 is a semi-circular groove or vsocket 1 toreceive the transverse cylindrical projecting bearing member 5 whichcooperates'with the socket toform a knuckle joint. The forward last face6 of the heel part 'I of the last is cut away so asto permit the lastparts to collapse. The lower adjacent faces of the last parts designated8 and 9 engage when the last is in its expanded position below theknuckle joint to limit the extent, of the expansion. The heel part 01the last is provided with a cut away slot 10 for receiving the springand link. Transversely of this cut away portion is located the heel partanchor pinll upon which is mounted the rear end of the links '12 whichconnects the last parts together. These links are spaced to receivebetween theinthe lever and spring hereinafter mentioned. These they arepivoted on the stud 13. This stud 13 is carr ed by the lever 14,- oneend of which is pivoted on the anchor pin 15 in the toe part of the lastwhich crosses the lower part of-theslot 2 in the toe part of the linksproceed forwardly to a point where I last. This lever-above thepin 13proceeds I forwardlyland' rearwardly in a-gentle curving arm forming alever arm 16 Which terminates above the anchor. p111 l1 and descendsdownwardly in the form of a book. 17 around the anchor pinsll and 15will not, however,

pass over this centerpoint when the parts are moved.

It will be observed that due to the use of the lever 14 and the leverarm 16 it is pos sible to get considerable leverage ;of the spring 17and to place that spring solely within theheel part and at the pointwhere it will have the maximum elfect. The lever and spring are.prevented from turning by being embraced between the links 12 as will bemore clearlyseen in Figure 2.

It will be understood that I desire to comprehend within my inventionsuch modifications as may be necessary to adapt it to varying conditionsof use. 1

Having thus fully described my invention, what I claimas new and desireto secure by Letters Patent, is

' 1. In a, last, a toe part and a heel part adapted to rock one on theother, a link joining said parts, an anchor pin in one lastpartsupporting the link at one end,a

other end, an anchor pin in the other last part for supporting saidlever, and means attached to said lever projecting from said lever inone last part to a point within the other last part for supporting aspring, and a spring engaging said first mentioned last part.
